I'll be interested to see how you go Stefan - is it seeing or collimation.
My Mars images look similar - some night worse than others. I'm using a 1000mm focal length newt with a 2x barlow. I've collimated my scope with an orion cheshire collimator and a laser collimator (which I've also collimated). Then I've tweeked it with an out of focus star when the scope has cooled. So I'm sure it seeing, rather than collimation - or I'm not getting good focus ..
